Title: Transmission line protective system
Inventor: TANAKA TOSHIO
IPC: G01R19/00
Filed: 1991-06-06
Abstract: PURPOSE:To get a protective system which does not require the compensation of an FM modulating circuit, transmission delay time, etc., by detecting the currents at the self ends and the opposite ends of a transmission line with optical CT's, and inputting these optical signals into the protective relays at the self ends and the opposite ends through optical fibers. CONSTITUTION:The currents of the self ends and the opposite ends of a transmission line are detected with optical CT's 2, and output optical analog signals. These optical analog signals are divided to self ends and the opposite ends by an optical branching filter 4, and input them into the protective relays 6 at the self ends and the opposite ends through optical fiber 5. The protective relays 6 detect the phase differences between each analog signal being input from self ends and the opposite ends, and in case that the phase difference becomes above a specified value, it judges it to be an internal accident, and outputs as trip signal to CB7. CB7 performs trip operation and cut off the accident by the trip command from the protective relay 6. Hereby, highly accurate phase judgment can be performed even if the correction of the signal transmission time difference is not executed yet.

CONSTITUTION:A compressor 1 is operated while closing a discharging valve 5 and opening a bypassing valve 7 and a suction valve 6. The compressor 1 sucks refrigerant from the pipeline 17 of suction side, compresses it and the compressed refrigerant is condensed in a condenser 2 and the condensed refrigerant is collected and recovered into the pipeline 16 of discharging side and a refrigerant tank 8. The predetermined amount of the recovered refrigerant flows into the suction side pipeline 17 through the squeezing mechanism 9 of a bypass pipeline. Refrigerant in the pipelines and respective instruments is sucked into the compressor 1 through a pressure reducer 3, an evaporator 4 and the suction side pipeline 17. As the recovery of the refrigerant is advanced, the suction pressure of the compressor 1 is reduced and the compression of the evaporator 4 and the refrigerant pipelines have become a constant condition, the suction valve 6 is closed to stop the compressor 1. According to this method, the refrigerant is collected and recovered in the circumference of the compressor 1 whereby the recovery of the refrigerant is finished.

Abstract: PURPOSE:To easily attach a commodity nameplate despite its size slightly different from a prescribed size and to prevent the warp of the nameplate by attaching close to an electric illumination plate and pressing the nameplate with the backward spring force by means of a nameplate holder plate. CONSTITUTION:When a commodity nameplate 4 is attached, a nameplate holder plate 6 is held at a moved-back position with operation of a stopper mechanism 10. Then the nameplate 4 is hanged down at the front side of an attachment frame body 5. Then the mechanism 10 is released and the plate 6 is energized forward by a spring 8. Thus the nameplate 4 is pushed forward from the back side by the plate 6 and held close between an electric illumination plate 3 and the plate 6. Thus the nameplate 4 is attached close to the plate 3 so that the display contents of the nameplate 4 can be easily viewed from the front side. Furthermore the nameplate 4 is never warped during its use even in humid environment. As a result, the nameplate 4 is surely attached despite its size slightly different from a prescribed size and at the same time the warp of the nameplate 4 is prevented.
